Cl. 1088 1 Claim ABSTRACT OF THE DISCLOSURE An adjustable table forsupporting papers, books or a tray of food, and which includes avertically adjustable stand upon which there is a tilt adjustabletable-top.

This invention relates generally to adjustable tables.

A principal object of the present invention is to provide an adjustableeasy chair table which can be used particularly when a person is sittingin an easy chair and wishes to have a convenient surface upon which towrite or hold reading matter.

Another object of the present invention is to provide an adjustable easychair table which is readily adaptable for being used by persons restingin bed and which may be used to support a book in a convenient inclinedposition, a tray of food in a horizontal position or which may be usedfor writing upon papers, the table top being inclined to any desired,comfortable angle.

A further object of the present invention is to provide an adjustableeasy chair table which incorporates a stand that is verticallyadjustable to any convenient elevation.

Yet a further object of the present invention is to provide anadjustable easy chair table wherein the table top may be convenientlyadjusted in tilt by a simple control knob.

Other objects of the present invention are to provide an adjustable easychair table which is simple in design, inexpensive to manufacture,rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIGURE 1 is a perspective view of the present invention;

FIGURE 2 is an enlarged cross-sectional view taken in the line 22 ofFIGURE 1; and

FIGURE 3 is an enlarged cross-sectional view taken on the line 3-3 ofFIGURE 2.

Referring now to the drawing in detail, reference numeral represents anadjustable easy chair table, according to the present invention whereinthere is a stand 11 and a table top unit 12.

The stand 11 comprises an upstanding tubular post 13 which is rigidlyaffixed at its lower end to a generally U-shaped base 14 which includesspread apart legs 15 which rest upon a supporting surface such as afloor. The upper end of the post 13 is open so as to allow a bar 16carried within the tubular post 13 to protrude upwardly therethrough. Asis shown in FIGURE 3 of the drawing, the bar 16 may be likewise madefrom tubular material, or if preferred it may be of solid rod. A U-shaped key 17 is formed upon the post 13, the key extending radiallyinwardly to fit within a keyway 18 formed upon the bar 16, therebypermitting longitudinal movement respective between the parts butpreventing rotational movement therebetween. A threaded opening 19 isprovided in the side of the post 13 for purpose of thread- 3,435,783Patented Apr. 1, 1969 ingly engaging a screw 20 having a knob 21, theend of the screw serving to abut against the side of the bar 16 andretain the same in locked position respective to the post. At the upperend of the bar 16 there is a cross-arm 22 having a threaded opening 23therein for receiving a screw 24 having an enlarged head or knob 25.

A washer 26 is placed against the upper end of the post 13, a bearingblock 27 being placed adjacent the upper side of the washer, and atoothed gear 28 being placed adjacent the upper side of the bearingblock. The bar 16 extends through the washer, bearing block and gear 28.

The table top unit 12 comprises a fiat board or panel 29 mounted upon aframe 30 having a plurality of upwardly extending screws 31 therethroughfor engaging the under side of the panel 29, and securing the samethereto. The frame has a downwardly extending portion 32 at onelongitudinal end, the downwardly extending portion being rigidly affixedto a sector gear 33 having teeth 34 which are in engagement with teeth35 of the gear 28. An opening 36 extending through the sector gearprovide means for insertion of the screw 24 therethrough.

In operative use, when it is desired that the stand be adjusted inelevation upwardly or downwardly, then the knob 21 is rotated to loosenthe hold of the screw 20 against the bar 16 and thereby allowingvertical move ment of the bar 16. When the bar 16 is raised, the tabletop unit may be rotated pivotally respected to the direction of the legs15 after which the table top unit may be lowered to cause engagement ofsector gear with the gear 28.

When it is desired that the table top unit be tilted in either directionand to any desired convenient angle, the knob 25 is turned to allowpivotal movement of the table top unit respective to the stand. Thus theteeth 34 are selectively engaged to teeth 35 of the gear. Thereafter theknob 25 is again tightened.

While various changes may be made in the detailed construction it isunderstood that such changes will be within the spirit and scope of thepresent invention as is defined by the appended claims.
